Hi
  Here I tried like
email_array = Contact.get_email_ids_of_contacts(problem.reported_by_id) 
unless problem.reported_by_id.empty?
       It worked and I got the two mailIDs But when I add the next line 
like
email_array = email_array + 
Contact.get_email_ids_of_contacts(problem.analyst_id) unless 
problem.analyst_id.empty?

     Now it is not working What might be the cause.Please help

Note:
  In get_email_ids_of_contacts of Contact model just wrote
return 
Contact.find_by_id(contact_id).contact_email_addresses.find(:all, 
:conditions => ['contact_email_address_type_id=?',2]).collect { |mail| 
mail.email}

Sijo
